Question

the perimeter is 54cm^2and length is twice its breadth of a rectangle. find both length and breadth. ​

Answer 1

let breadth be x

let length be 2x

perimeter=2×(l+b)

54 =2×(x+2x)

54 =2×3x

54 =6x

54/6=x

9=x

breadth= x=9cm

length =2x=2×9=18 cm

Answer 2

Answer:

Length = 2*9 = 18 cm.

Step-by-step explanation:

The length of a rectangle is twice its width. If its perimeter is 54 cm, what is its length?

My dear friend Prakash Joshi,

It is so quite simple question just follow the condition of the questions, Nothing else.

Let suppose that the width of the rectangle be W = x

Then the length of the rectangle be L = “2x”

Given data :- the length of a rectangle is twice it's width. And the perimeter is 54 cm .

Find out the length of the rectangle =?

We know that the perimeter P =54 cm

2(L +W) =54

2(x+2x)=54

6x=54, x = (54/6)=9 cm. answer

So the width of the recatngle W =x = 9 cm

Then the length of the recatngle L = 2x = 18 cm answer.

I hope that your doubt will be cleared up.

Stay safe # stay tuned.

Thankyou,
